This is what I used to make mine work.

And pin#3 direct battery fused at 30 amps spliced to feed pins 30 of ASD and Pin 30 of fuel pump relay
Pin 9 IGN switched voltage spliced to feed 12v side of ASD and fuel pump relay.
Pin 11 and 12 grounds.
Pin 29 to brake switch
Pin 30 to park neutral switch
Pin 51 Switched ground wire to Pin 86 on ASD and fuel pump relay
Pin 57 pin on 87 on ASD relay
I also had a 1994 Dakota Service manual and a good understanding of
electronics. Hope this helps I think you may still find this in the tech archives also

Awesome. THANKS!!! up

Dont let the amount of wires scare you. I just hung the ECM end of the wires from the ceiling and saved all the sensor and feed wire wraps from the factory. You just need to feed the ECM power for memory and Ignition.
The 2 relays feed power to the fuel pump,And the ASD relay keeps things running if there is no problems. OBD1 is quite simple information in information out..

IIRC the 80's injected Chargers and maybe others used a speed sensor that connected to the trans and then the speedo cable connected to the sensor so you could have both. I don't know if they used the same counter though. But I think there are only 4 poles in the sensor. If you keep the speed sensor and brake light switch signals you won't have to use switches for the O/D and lockup.

I'm going to swap a complete 93 Ram Charger dash, engine, HVAC, fuel tank and wiring harnesses into my 74 crew cab. I plan to use everything from the RC including the steering column so mine should be easy. What I would like to do though is an OBD II swap for the engine management so I can modify the engine with an intake, cam and heads. The hot wire harness looks like an easy way to go but at $1000 it's pretty steep. Especially when you consider you still have to get a PCM and tune it as well. So it may remain stock for awhile.
The Scamp is sold, now just two old trucks.
'92 D250 Club Cab CTD, 47RH conversion, pump tweaks, injectors, rear disc conversion. Hydroboost coming soon
'74 W200 Crew Cab 360, NP435, D44, D60 and NP205 divorced transfer case. Magnum 5.2 MPI coming soon.

STANDARD MOTOR PRODUCTS SC108 is the sensor for older transmissions that lets you keep the cable and still have an electronic signal for the computer. But you'd need the pinion adapters to put into the 95 setup.
